Not many people outside of Azerbaijan know the capital of Azerbaijan. And since the TTS engine pronounces it incorrectly as "Bako," somebody could spell it "Baco" and end up with a loss of hearts for no reason. Playing the "random proper noun" game really doesn't work with a language written in an Abjad.
(12 Nov 2020) -- And Azerbaijan and Baku have been in the global news more than usual lately -- Azerbaijan vs Armenia war -- and especially in M.E. news, due to reports of Syrian-rebel mujaahidiin/mercenaries and Israeli provided drones and other military gear (on the Azeri side) -- so maybe it's good for anybody aspiring to read Arabic language news feeds to recognize باكو at sight -- also, BTW, Google Tran rendered Baku that way for both Arabic and Persian/Farsi --
